Bells of Steel 60 mm (2.3 in) racks: what the label means

Bells of Steel labels its 60 mm tubing 2.3 in, though 60 mm calculates to about 2.362 in. Its Sandwich J-cups come in a 60 mm version, 880 lb combined.

Also listed as 2.3 in racks

Short answer

Bells of Steel says every one of its racks uses either 2.3 x 2.3 in (60 x 60 mm) or 3 x 3 in tubing. 60 mm calculates to about 2.362 in, and Force USA labels its own 60 mm MyRack 2.4 in, so the label alone does not show that parts cross between brands. Bells of Steel sells a 60 mm version of its Sandwich J-cups for 60 mm racks with 5/8 in holes, listed at 880 lb combined.

Watch out for

  • Bells of Steel's Sandwich J-cup page lists a 2.3 x 2.3 in version and a separate 60 mm version, both for 5/8 in holes. Pick the variant that names your rack.
  • Bells of Steel lists the 60 mm Sandwich J-cups at 880 lb combined without stating the basis, and states no locking method for them; only the Manticore version lists mag pins.
  • Force USA labels its 60 mm MyRack 2.4 in. The same tube size under different labels does not show that parts cross between the two brands.

Questions

Is a 2.3 in Bells of Steel rack the same as 60 mm?

Bells of Steel labels its 60 x 60 mm tubing 2.3 x 2.3 in. Calculated from 25.4 mm per inch, 60 mm is about 2.362 in, so 2.3 in is a rounded label, not a measurement.[1][2]

Do Force USA MyRack attachments fit a Bells of Steel 60 mm rack?

Neither maker says so in the sources we read. Both use 60 mm tubing, but Bells of Steel labels it 2.3 in and Force USA 2.4 in, and a shared size or label does not establish cross-brand fit.[1][6]
